That is a really nice sporter, and one with all the right stuff. The Pacific (and its cpies) peep sight is easy to lose in the field unless you loctite the big screw down. Don't ask me how I know this. There are better aperature sights, including the Williams FP-krag which may still be available new, also sometimes you can find an older Redfield for the Krag- both sights heve better windage and elevation adjustments than the Pacific.
Unique is great powder. It just takes a little and it lights up easily even in a large cartridge. It is very predictable.
Good luck!
